Calculation of the power density of the nuclear fusion reactions plays an important role in the construction of any power plants. It is clear that the power released by fusion reaction strongly depended on the fusion cross section and fusion reactivity. Our calculation concentrates on the most useful and famous fuels (Deuterium-tritium) since it represents the principle fuels in any large scale system like the so called tokomak.

The measurement of uranium concentration in human urine is very important in assessment of occupational and public exposure to uranium. In the present work, the fission track technique was used to decide uranium concentration in blood of Kidneys Failure Patients in Al- Muthanna Governorate. The uranium concentration values in urine samples of Kidneys Failure Patients ranged between 0.92 to 4.87 , while Healthy group results were ranged 0.91 to 1.82 . Results showed that the concentration of uranium in the URINE increases in kidney failure patients.

Precise the measurement of uranium concentration in human blood is quite important in assessment of occupational and public exposure to uranium. In the present work, the fission track technique was used to determine uranium in blood of Kidneys Failure Patients in Al- Muthanna Governorate. The uranium concentration values in blood samples of Kidneys Failure Patients ranged between 0.119 p.p.m to 0.31 p.p.m, while Healthy group results were ranged 0.117 p.p.m to 0.199 p.p.m. Some parameters used to explain the results of uranium concentration. Results showed that the concentration of uranium in the blood increases in kidney failure patients.
